To all whom it mayv concern: 1

Be it known that we, DAVID J WHITE and DAVID H. HANNA, citizens of the United States, residing at Oil City, in the county of Venango and State or Pennsylvania, have invented certa'in new and useful Improvements in Continuous Frogs for Rallways, of

which the following is aspecification.

The primary object of this invention is, to supply a continuous frog for railway tracks whereby the'usual gap between the throat and the point of the frog'will be obviated, thus avoiding the dropsfof the car wheel as it passes through the frog.

Another object of our invention is, vide means i. for locking the shifting, railalining or continuing member in its proper functional position whereby any acc dental or displacement of said member is 1 shifting avoided.

The construction whereby we attaln sald objects is clearly shown in the drawings which form a part hereof, the various figures of which are as follows:

Figure l is a plan view of our improved continuous frog.

Fig. 2 is a section on line IIII of Fig. 1.

Fig. 3 is an inside elevation of one of the alining-rails, the connecting cross-piece or guide block being shown in section.

Fig. 1 is a section on the longitudinal center line of'Fig. l, and on line IV-IV of Fig. 2.

Fig. 5 is a plan view of the sole plate, stripped of the cooperating elements.

Fig. 6 is a plan view of the shiftable, alining-rail structure. I

Fig. 7 is a side elevation of the alining rail structure.

Fig. 8. is a side elevation of the lockingdogs and the actuating block by which both said dogs and said shiftable structure are actuated. t y

We will now describe the construction illustrated by said drawings, in a manner suficiently full, clear and exact to enable those skilled in the art of railway-track con- 'struction to make and use our continuous fro T he point of the frog is indicated by the numeral 1. 2 and '3 are the converging rails between which and said point 1 a continuous, alining rail structure is to be supplied. 2 and 3 are the shiftable alining or continuing-rails adapted to form the continuing elements or sections between and converging to pro- Specification of Letters Patent.

rails 2and 3 and said point I. Said con-. tinuing rails 2 3" are firmlyand rigidly united by means of the guide-block 4:. All of said supplementary-rail structure is preferably-formed as a unitary stru'cture,see

Figs- 6 and 7. i

Said supplementary, or alining rail structure, Fig. 6, is operatively' mounted'upon a sole/plate 5 shown in Fig. 5. A transverse groove is formed. inflsaid sole plate for the reception of said guide-block 4:. .A groove isformed in each of the longer edges of said guide-block 4 for the reception of the retaining plates 8, 8; said plates are attached to the sole-plate '5 in any suitable: manner,

as by screws 9.

For the purpose of actuating said supplementary,al1ning rail-structure into-its respective alining positions, we provide an actuating block 10 which occupies a groove in the lower face of said guide-block 4:, andis adapted to have longitudinal movement therein. Said actuating block 10 is provided with a lug 11 for the attachment of any operating means, 12, suitable for the purpose, and to be determined by the class of service or traflic over the road at the location of the frog. An opening 11 is provided in the sole plate 5 for the reception of said lug 11.

Each end of the actuating block 10 is provided with a cam-lug 13 the inner, opposing faces of which are vertical and adapted to engage the adjacent faces of the abutments 14 of the alining-rail structure. The upper faces of said lugs 13 are formed into outwardly-sloping faces 15, 15 which are adapted to cooperate with correspondingly-formed faces upon the under side of the respective adjacent ends of the lockingdogs 16 and 17 the ofiice of such cooperation being to suitably actuate said dogs, especially out of the locking position into the position occupied by the dog 16, the do 17 being shown in its locking position. he outer ends of said dogs are hinged to the sole-plate'5, and for this purpose the hingepin lugs 19, 19 are provided upon the outer ends of the wings 18, 18. Each of said dogs 16 and 17 is provided in its outer end with a pin-socket 20 for the reception of the hingepin 21, whereby said dogs are adapted to have free vertical swinging movement.

The distance between the vertical faces of the actuating lugs 13, as indicated by the dimension w in Fig. 8, is somewhat greater than the distance between the outer faces of the for the amount of lock-actuating movement,

indicated at z in said Fig. 2 before said actuating lug 13. comes into eontactwith abut ting face of its respective abutment 14.

During said movementz the cam-face sim pinges upon the corresponding face of the locking dog 17 and causes said clogto rise from its lockingposition, and thus to'perinit the sliiftin movement of the alinin rail structure, which is also accomplished by said actuating block 10 as itcontinues its movement in the same direction; when this last-mentioned shifting movement is completed, so that the rails 2 and'2' are properly alined, dog 16 drops down and locksvthe alining st'ructlure'in its functional position.

We claim thefollowi-ng-z combination, fixed frog-point; two fixed vrails converging toward lou't not meeting said point, an alining rail-structure eomprising two rigidly-united rail ,menibers shiftable to form a continuous rail between either of said converging rails and said point, means operableto shift said "rail structure, and means automatically locking said shiftable structurin either of its functional positions. a 2.- A. continuous frog for railwayscomprising in combination, a sole plate, a frog poi ntpartial'ly' carried by said sole plate,
